- pass string size to BLI_timestr() to avoid possible buffer overrun.
- quiet warning for mingw.
- include guards for windows utf conversion funcs.
- fix for mistage in edge-angle-selection check.
- some style cleanup.

Fixes a warning from GCC 4.7.2.

Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...

* The minimize() function, which solves a least-squares problem, is
only needed for sharp remesh mode, but was being calculated for
smooth and blocks modes as well. Disabling this calculation when
it's not needed gives a big performance boost.

* Move InternalNode operators from Octree class into InternalNode
struct
* Constify various member functions

Changed one of the intersection tests to use < rather than <=
The sharp and smooth modes look fine now for the special case that was
reported broken; blocks mode looks correct but "jumps" slightly from
one octree resolution to another, so may need additional corrections.

Removed a lot of unused code, added comments and some clearer
naming. Minor code shuffles and style cleanup too.

Reading in triangles now skips any NaN coordinates.

The changes mostly center around two new structures, InternalNode and
LeafNode. These provide an explicit representation of the Octree
nodes, which formerly were manipulated as opaque byte arrays.
A fair amount of commented out/unused code was also removed. This
includes the "CINDY" code, which may yet be useful, easy to bring back
if so.
There should be no difference in the output of the remesh modifier,
but memory usage may be slightly different. The flood fill bytes are
no longer optional; they will be allocated whether or not the 'remove
disconnect components' flag is set. The leaf node is probably not as
tightly packed due to alignment issues; this could be fixed with the
__attribute__((packed)) flag in gcc (probably there's an MSVC
equivalent), but not sure it's worth it. The internal nodes should
take up less space on 32-bit systems, allocating sizeof(pointer) now
rather than constant eight bytes.
These changes were made in persuit of bug #30158 (remesh crashes on
PowerPC). There's still a fair amount of bitwise stuff in the Octree,
so may still be endian issues and not yet sure if this fixes the bug,
but should be much easier to track down problems now.

without the underscores these clogged up the namespace for autocompleation which was annoying.

This patch adds a new remeshing modifier. The algorithm is based on
the paper "Dual Contouring of Hermite Data", and the implementation
was contributed to Blender by Dr. Tao Ju.
The contributed code is in intern/dualcon, and was modified to compile
under gcc and work on 64-bit systems. Files not needed for Blender
were removed and a small C wrapper was added in order to interface it
with Blender. The rest of the patch is just standard modifier stuff.
